What comes after Tier-3?

<p>I've been on this board less than a month. I already vaguely knew what "Tier 1, Tier 2, Tier3" meant, and just added T10 and T14 to my vocab. (Along with UGPA, LSAC, FA, etc. I thought only engineers used acronyms.:))</p>

<p>Is Tier-3 considered the lowest rank of (accreditted) law schools? Or does it go lower than Tier-3?</p>
